Abstrakt: We report a 94-GHz large-signal load-pull characterization of InP/GaAsSb double heterojunction bipolar transistors. The investigated devices have an emitter area of 0.20\,\times\,9.5~\mum^2. Biased for highest power added efficiency (PAE), an output power of 6.62 mW/\mum^2 (11 dBm), a power gain of 5.2 dB, and a PAE of 27.7% have been obtained. Biased for highest output power, 10.26 mW/\mum^2 (12.8 dBm) has been achieved without significant degradation of the PAE (25.2%) and the power gain (4.5 dB). [ABSTRACT FROM AUTHOR]
